This is one of my favourite mushrooms, not really for eating but mainly because of it’s attractive colours and fantastic commonly used name!

Tricholomopsis rutilansSimply called Plums and Custard (Tricholomopsis rutilans) this very common mushroom almost looks good enough to eat, and even sounds good enough to eat, but before you get too excited, the general consensus is that it’s just not recommended. Too watery, unappealing with a bitter or unpleasant taste. Mind you, I’m not really much a fan of the real dish!

When you first stumble across this mushroom, the first thing you notice is it’s striking purple cap (sometimes with a reddish tinge). On closer inspection you’ll notice that purple effect is made up of many purple/reddish flecks or scales on a predominately yellow cap. They’re are usually denser at the centre, appearing darker. The same colour features on the stem are similar to the cap, but the fine purple scales are less profuse.

On the underside you’ll find the distinctive rich yellow gills, which in my opinion, actually do have an uncanny hue of custard.

The size of this mushroom varies from place to place and can grow quite large. But basically the cap dimaetre ranges from as small as 4cm up to 12cm. I also read somewhere that one specimen at an Italian mushroom show had an unusually large cap of 56cm in diametre. Now that’s big!

Next time you’re out in coniferous woodland during the usual mushroom season (September – November) keep a look out for these beauties growing on or around dead wood or old stumps. Shame we can’t actually eat them. Not for pleasure anyway!

There’s a small stretch of coniferous woodland close to where I live, and over the  years I have never seen such a variation of mushrooms, toadstools and fungi in such a relatively small place. Great stuff!

Clitopilus prunulusAnd today was no disappointment either. Poking out of above the leaves in a small clearing were the caps of a small group of Miller mushrooms (Clitopilus prunulus).

This was the first time I’d seen them here and I needed to check all characteristics of this wonderfully edible mushroom (as I always do) but especially this time as they were very close to the woodland/grassland border. The poisonous Fool’s Funnel (Clitocybe rivulosa) – a grassland species – is a sinister looking double for our tasty Miller mushroom.

The Miller has a pink spore print, so I also needed to be aware of confusion with other poisonous species with the same feature. For example, the Livid Pinkgill (Entoloma sinuatum), although not looking too similar, is quite an unpleasant toadstool.

The main  identification markers were all there (see ID table below) – the size, the wavy irregular shape, the soft leathery (kid glove) texture, decurrent gills (that came away easily from the stem and cap), and of course the strong floury (mealy), raw pastry odour were all unmistakable.

The gills of this mushroom are initially white, then change to a mild pink colour as they mature (hence the pink spore print mentioned earlier). But to be on the safe side, I would always recommend you take a spore print (see how to make a spore print), just as I did, to doubly make sure.

Unfortunately these beauties were being systematically killed off inside from larvae infestation. They started at the base, munched up the stem and into the cap. I’m not sure if this killed off the spores developing properly or all spores had been shed (which I’m not convinced about), but not even a single spore had dropped to make any kind of print. Needless to say, I didn’t eat them, but then I couldn’t anyway – maggot munchies anyone!?

There should be more elsewhere or on the way soon. They can be found in small groups, and interestingly have some biological link with Ceps (Boletus edulis), so take a look around to see if there are any nearby. Good luck…

I have a good gauge for the start of the mushroom season in the UK* – and that is my birthday! Well, the birth month anyway. Mushrooms grow all year round, but they are never so much in abundance and variety until the beginning of September. It’s technically still summer, but I can sense the autumn changes already in the wind (and rain of course)! So when people say ‘When does the mushroom season begin?’ I always say – ‘You can’t go wrong from September to November, get yourselves out there for the best pickings…’

Spiny Puffball (Lycoperdon echinatum)I especially notice the puffballs first. I don’t know if this just a Leicestershire thing, but I always find them in abundance, on grass or in woodland, keen to get going. As I walked in the woods today I found at least three different types of woodland puffball without really having to look that hard. They definitely like to get started early!

I chose to feature the Spiny Puffball (Lycoperdon echinatum) because I hadn’t taken pictures of it before. It’s a great looking  and slightly unusual member of the puffball family. Often hidden from view, it blends in very well with the undergrowth (depending on their age). They start off white but soon turn to neutral brown colour, although the short stem can remain white for longer.

It’s most noticeable feature of course is that it’s covered in many tiny spines or spikes. These are finer and less pyramidal than the Common Puffball and naturally a different colour. After time some of these spines can become detached from the main body, leaving a cellular-like pattern, usually before the puffball opens up at the top to disperse it’s spores. Unfortunately I have no current example in the photos shown here.

Dimensions are also similar to the Common Puffball except for the shorter stem, and live in a similar environment. The Spiny Puffball prefers deciduous woods (and sometimes heaths) whereas the Common Puffball is in any type of woodland (deciduous or coniferous).

The young inner flesh looks quite nice, but this puffball is unfortunately classed as inedible, and I don’t know why. Perhaps the taste is disagreeable and unpleasant. I really didn’t feel like trying. There’s plenty more edible mushrooms on their way.

Let the season begin…

*In the US (Pennsylvania) a popular mushroom festival coincidentally started this year on my birthday! (http://www.mushroomfestival.org/). If you’re over near that way, it’s definitely worth a look.

Although this is a very common species of mushroom, I don’t come across them that often. Even though mainly white in colour they always seem to be hiding under bracken or disguise themselves in similar woodland undergrowth.

Collybia maculataBut once seen, never forgotten, the Spotted Toughshank (Collybia maculata) is a nice looking, creamy white, chocolate sprinkled mushroom. Although I should really say Toadstool as it is inedible (tough and bitter) and there really isn’t any chocolate involved! If only…

I found this lovely group of ‘toughshanks’ (common name for the Collybia genus) in some mixed woodland, near the edge of a grassy woodland path hiding in the undergrowth. They can be found in both deciduous and coniferous woodland but they tend to favour coniferous trees – like this group.

The caps are initially a clean (slightly creamy) white colour, but soon distinguish themselves with the characteristic of having brown spots or freckles on the cap. These tan brown spots can sometimes merge or not be as contrasty against the white cap, so it may sometimes appear as one blended brown patch, especially at the centre. When younger the caps are dome shaped but flatten out with age and sometimes get wavy at the edges.

On the underside the crowded gills (free from the stem) are also white and, in a similar fashion to the cap, become spotted dark brown with age.

The stem is also a great identification marker too. As with all Collybia species, the ‘shank’ is tough, fibrous and flexible. None of this genus have rings present either. As you see in the pictures they can also grow quite tall (up to 12cm), markings are similar to the cap, but mainly white and the longer stems can sometimes be slightly routing.

So be on the lookout anytime this summer to late autumn. They’re out there, but also like to to hide! See the extra ID notes below for further information…

It’s very rare that I do not see one of these bracket fungus when I’m out and about on a forage. They grow quite large and are around all year. It would be hard to miss one.

The Birch Polypore or Razorstrop fungus (Piptoporus betulinus) is an extremely common polypore fungus. As the name suggests, it is found exclusively on birch trees.

At maturity they are typically semicircular or kidney shaped as they grow outwards from the tree body. Shapes and sizes may differ a little but generally this is the norm. As I mentioned earlier, they can grow to a good size – between 20 – 30cm across and 8cm thick! They’re quite a sight to behold when they get to this size.

The colour is that of pure white (when younger) and as it matures it changes to a dull grey or tawny brown. It’s smooth surface often cracks, showing white flesh underneath. The consistency is spongy or slightly rubbery to the touch. These fruiting bodies can usually last from one year into the next, that is why you can see them all of the time over the winter months.

On the underside the pored surface is smooth and pure white, but over time this gets marked with dark patches from age and/or insect attack.

I know what you’re thinking though. Is this fungus edible? Well, unfortunately not. It actually smells quite pleasant but it’s taste is quite bitter. It’s a shame, I know.

At least it had it’s uses even as far back as 5,300 years ago! In 1991 “Ötzi the Iceman”  (Europe’s oldest natural human mummy) was discovered by German tourists in the Alps. Found in his possession were two species of polypore mushroom. One of which was the Birch Polypore (for medicinal use) which is known to have antibacterial properties. It could have also have been used to sharpen blades or tools – hence the name ‘Razorstrop’.
